Eikichi learns of a hidden treasure somewhere on one of Okinawa's islands and decides that a special class trip is in order.
...in order to find
the buried treasure, didn't you?
كي تجِدَ الكنز المدفون ، أليس كذلك؟
um einen vergrabenen
Schatz zu finden, oder?
para encontrar un tesoro, ¿verdad?
para encontrar un tesoro, ¿verdad?
para encontrar o 
tesouro escondido, não?
